TENSIONING DEVICE FOR TENSIONING A HELICAL SPRING
The invention relates to a tensioning device (01) for tensioning a coil spring (02) that is supported on a main shaft (03) and at a fixed end is rotatably fixedly connected to a frame. The tensioning device (01) includes a gear drive (05), having a first gear element (06) that is axially displaceably guided on the main shaft (03) and rotatably fixedly connected to a free end of the coil spring (02), and having a second gear element (07) that is in drive engagement with the first gear element (06) in order to set the first gear element (06) in rotation about the main shaft (03). The tensioning device (01) also includes a retaining element (19) that holds the second gear element (11) in the position of drive engagement with the first gear element (06). Furthermore, the tensioning device (01) includes a drive element that is coupled to the second gear element (12) in order to set it in rotation. The gear drive is formed as a bevel gear transmission, wherein the first gear element (06) is formed as a bevel gear (06) and the second gear element (07) is formed as a bevel gear pinion (07), and wherein the rotational axes of the two gear elements (06, 07) extend perpendicularly to one another. The bevel gear (06) is integrally connected to a guide bushing (10), and has a central opening (09) through which the main shaft (03) extends, and has a cylindrical receiving section (12) in which the free end of the coil spring (02) is fastened.
